The correct option is A Wind
Pollination in Cycas is by the wind.
Anemophily also n called as wind pollination is a type of pollination whereby the pollen is distributed by the wind. Almost all gymnosperms are anemophilous, as are many plants in the order Poales, including grasses, sedges and rushes. Other common anemophilous plants are oaks, sweet chestnuts, alders and members of the family Juglandaceae. Very few varieties of Cycas pollinate with the help of birds as pollinating agents.
